The Celdé stereoscope was manufactured in France,
but at this time no date of manufacture can be definitely established.
The price on the box shows it costs 300 Francs. The viewer was made
from rigid cardboard coated with a black paper covering. The inside of
the stereoscope slid in and out to allow focusing. The glass
lenses were mounted into an early type of
plastic surround, which, in turn, was glued into the body of the viewer.
In construction the viewer was very similar to the French Bruguiere No 1
viewer

This type of viewer took rolls of stereo pictures
on film which were fed through a slot at the rear of the stereoscope.
The films were stored in cardboard rolls.

The company name and address appear
on the bottom of the box, they are
